List of bus routes in Hong Kong

The following is a list of current franchised bus routes in Hong Kong, sorted according to bus companies. All current franchised bus routes are operated by air-conditioned buses only. Note that Hong Kong Island, Kowloon and New Territories and Lantau Island have their own, separate route numbering systems.

One open-top bus was deployed on this route between 17 January 2000 and 27 September 2014 (DA66 was officially de-registered on 12 November 2014 after completing 18 years of lifespan).
Formerly route 626, this has been absorbed by NWFB route 15C in 17 January 2000.

The large majority of bus routes in Kowloon, New Kowloon and the New Territories are operated by Kowloon Motor Bus. Only in recent years has New World First Bus acquired routes serving West Kowloon and Tseung Kwan O. Those routes all have 3 digits and begin with the number 7.

These routes are not franchised routes, but the areas served by the LRT are a franchised area of the KCR Corporation / MTR Corporation Limited, and other bus companies were not allowed to run similar local routes in the northwestern New Territories until this restriction was lifted in 2006.

All cross harbour routes have 3 digit route numbers. Routes travelling through the Cross-Harbour Tunnel begin with a "1", and are shaded red. Routes travelling through the Eastern Harbour Tunnel begin with a "6", and are shaded red. Western Harbour Tunnel Routes begin with a "9", and are shaded green.

Most routes that begin with a "3" are morning express routes, with the exception of routes 307 and 373A. Note that special services of routes are not listed.

With the exception of route R8, all other Disneyland routes depart for Disneyland early in the morning, and will return to the urban areas after the final fireworks display of the day. If a passenger wants to take a bus to Disneyland at any other time, they must take a bus to the Lantau Link Toll Plaza and interchange to route R8.
